WITNESSES UNITED s'rnrns ARTHUR E. HARPER, OF NEWARK, NEW JERSEY, ANDHENRY H. RIGGS, OF HYDE PARK, MASSACHUSETTS.

PATENT cannon" FILM-CAMERA.

Specification of Letters Patent.

To all whom it may concern Be it known that We, ARTHUR E. llanrnn, aresidentof Newark, in the county of Essex and State of New Jersey, andllrizvnr H. RIGGS, a resident of Hyde Park. in the county of Norfolk andState ofM-assachusett's, both citizens of the United States, haveinvented a new and linproved Film- Camera, of which the following is afull, clear, and exact descri tin.

Our invention relates to an improvement in cameras," and moreparticularly to a film camera.

An'objectof our invention is to so arrange the exposure openingadjacentthe film that when desired onlya portion of the film may be exposed.

A further object of our invention is to permit the unwinding of the filmfrom the forward spoolwi'thont causing sagging or rumpling of the film.

With theabove andoth'er objects in View, as will more fully hereinafterappear, the

' present'i-nventionconsists in certain novel particularly pointed out-'in' r claims. 30 ing drawings,

travels across an exposure frame 5 having an exposure opening therein.

The front portion of the casing A is curved about the spools 1 and 3, asshown at (3, and is then stretched across the front of the camera toform a frame 7 constituting the bellows opening of the camera, saidfront portion extending in front of and spaced a short distance from theframe 5. Positioned between the frames 7 and 5, is an intermediate frame8 having an opening corresponding to the openings in the aforementionedframes, which frames constitute two parallel disposed guideways, intoeach of which guideway-s is positioned a movable shutter 9 of anysuitable material, preferably opaque celluloid, the inner end of each ofwhich shutters is reinforced by a transverse metal strip with aforwardly-projecting extension 9, the end of which is bent inwardly toform a sliding tongue 10 movable in slots 11 in the opposite sides ofthe frame 7. The outer end of each of the diaphragms or shutters -9 ispreferably made flexible in order to fit in the ends of the casing A-between the outer frame and the revolving spools 1 and? It will be seenby thls arrangement that Patented Sept. 23, 1913.1

theopeningto the film may be of an extent to take in the whole portionof the film which is unreeled, or either one or both of the shutters 9may be drawn toward the center of the exposure opening to limit the sizeof the exposed surface or to place the picture on one or the other halfof the unreeled portion of the film or in any other position on thisunreeled portion.

j Ordinarily it cannot be ascertained when using the film and setting"it for another exposure, whether or not the entire surface is needed,and in case 1t 1S desired to use but a the full opening, it 1s necessaryto rewind .part of the exposed filmback on the supply spool. To do this,and, at the same time, to

the same, there is positioned on each of the.

a ratchet 12, shown in dotted lines in.

. portion of this film' after it has been set for tion of the film bythd numbers which are customarily printed on the backs of films incommon use.

Many changes could be made llllll'le above construction and manyapparently widely diflerent embodiments of this invention could be madewithout departing from the scope thereof. It is intended that allmatters contained herein, in the above description, or shown in theaccompanying drawings shall be interpreted as illustrative and not in alimiting sense.

following claims is merely intended to cover all the generic andspecific features of the invention herein described and-all statementsof the scope of the invention, which,

as a matter of language, might be said to fall therebetween, and thatmaterials, sizes and relativities of parts are non-essential, except ascalled for in the claims.

Having thus described our invention, we

claim as new and desire to secure by Lettersv Patent:

1. In a camera, the combination of a ca ing provided with spool holdersand with a relatively thin portion located between said spool holders, abellows secured to said'thin portion and extending between said spoolholders, a plurality of shutters slidably mounted within said thinportion, and movable independently of each other, and means controllableat the will of the operator for shifting said shutters independently ofeach other in relation to said thin portion of said casing.

,2. In a camera, the combination of a casing provided with rounded wallsforming housings for spools, a frame located within said casing andprovided with rounded portions mating the curvature of said roundedwalls and spaced therefrom, and a pair of shutters slidably mountedwithin said casing and provided with flexible portions extending betweensaid rounded walls and the adjacent rounded portions of said. frame forguiding said shutters partially in curved paths, and means for shiftingrelative positions of said shutters.-

The combination of a casing provided. with a spool holder having acurved wall,

It is also to be- -understood that the language used in the said casingbeing further provided with an opening for exposing a film, a framehaving an opening re istering with said opening in said casing, saidframe having curved portions disposed adjacent to said curved wall andspaced therefrom, and a flexible shutter slidably mounted within saideasing and provided with a portion extending between said curved walland the adjacent portion of said frame.

l. In a camera, the combination of a cas ing provided with a passagewaya portion of which is curved, said casing being further provided withanopening registering with said passage-way, a frame provided with anopening registering with said passage-way, said frame being provided.further wlth a portion curved to mate the curvature of said wall, and ashutter slidabiy mounted within said casing and adapted to close saidopenings, said shutter being provided with a portion extending betweensaid curved wall and the adjacent curved portion of said frame.

5. In a camera. the combination of a cas' ing provided with an exposureopening and with a slideway disposed adjacent to said exposure openinsaid slideway having a curved portion and a flexible shutter mount edwithin said slideway for-the purpose of partially closing said exposureopening, said shutter being provided with a portion extending into saidcurved portion of said slideway.

G. In a camera, the combination of a case ing provided with 'a spoolholder having a curved wall, said casing being further provided with anexposure opening and with a slideway, a frame carried by said camera andprovided with a curved portion disposed adjacent to said curved portionof said spool holder and spaced therefrom, and a flexible shutterlocated between said frame and the adjacent portion of said casing, saidshutter having a portion extending between the curved portion of saidspool holder and the adjacent curved portion of said frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
